I think the front panel doesn't look too good in the one photo because of the lighting.

it just looks a bit roughly ground on the edges....

Of course, if you are planning an SE version with an outer case 'like wot I done', then the inner case does not matter too much as long as it shields the amp....so you could get away with a specially designed front panel.....you have any DIY skills or know anyone who can cut/bend sheet metal, etc? The front panel could be made out of 6mm perspex, laser cut, or brass, chrome plated, etc....world's your oyster, really! Especially if you live in an area where there are little traditional machine shops in the backstreets....

Hello guys...

I  bought a Lovely Cube a few months ago.

After many OPAMPs changes...
I found a HUGE improvement using the AUDIO-GD OPA-Earth.
It need a extension cord for fitting it inside the case (Cap Type - about 150-200mm).

There was an noticeable improvement in the sound extension.
More defined bass and treble.
More natural and spatial sounds.

Just great !!!


I will take some pictures soon...
